SPEGIFIGATION forming part of Letters Patent No. 515,491, dated February 2?, 1894.

Application filed April Z8, 1893. Serial No.472,16l. (No model.)

To all whom it may concern.-

Beit known that I, MELnNcTHoN HANFORD, a citizen .of the United States, residing at Malden, inthe county ot Middlesexand State of Massachusetts, have invented certain new and useful Improvements in Atomizers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to tigures ot' reference marked thereon, which form a part of this specification.

This invention relates to apparatus for delivering a liquid under pressure in the form of a iine spray.

The apparatus embodying my invention is intended for application particularly in the treatment of malt liquors, and said apparatus is used in connection with a pipe, which is intended to convey from the hopjack, so called, to the atomizer the Wort which is delivered in the form of line spray, and is suhsequently collected in a vat or reservoir for further treatment. This act of delivering the Wort or liquid under pressure to the atmosphere, not only cools it rapidly, but like- Wise aerates it and the process of brewing is expedited.

The object of my invention is to produce an apparatus which is adapted to deliver a continuous line spray; further it is to be of variable capacity and likewise constructed to deliver a spray of large volume, While the form of the spray may be varied to suit the size and shape of the receiving vats. Other peculiar and characteristic features will be fully hereinafter described.

The drawings represent in Figure 1. a vertical sectional elevation of an atomizer em bodying my invention. Fig. 2 is an end elevation showing the lsame in place and attached to the wall. Fig. 3 is a plan of a detlector plate, and Fig. a sections on lines y y, a; a' showing the diderent convexity of the deiiector plate.

The object of this invention is more particularly as above premised for use in aeratl ing beer Worts, and it consists in a short length of pipe 2 in the form of a T casting bored transversely to receive a rod 3 equipped at one end with a disk 4. adapted to co-operate with a cup-shaped plate 5 termed the detlector plate. This latter is removably attached to the under side of the pipe 2, Which preferably is closed at one end, and interiorly screw-threaded and united at the other end to a supply pipe 6 leading from the pumps (not shown). The detlector plate is made removable in order that plates of ditferentsizes or forms may be attached; in this Way the size and capacity et' the atomizer may be altered to suit not only vats of diierent sh apes but the size of the brewing plant.

To enable the atomizer to direct the spray in particular directions, I provide. the deflector plate in shape With variable convexity or with different inclinations, as shown in Fig. 4. Thus the ends may have an angle of thirty degrees from the horizontal, While the sides may be at forty live degrees, hence the spray can be directed into oblong vats. It the latter were circular the convexity of theplate would be the same at all points and the shape of the plate would be circular also.

One of the peculiar features is t0 provide for a variable but predetermined size of discharge orifice shown at 7 and the construction is to prevent the contact of the detlector-plate with its interior co-operating disk. In this Way when the apparatus is properly adj usted no variation can occur in the said discharge orifice and the best results are obtained, while in addition this disk is capable of movement to enlarge the discharge orifice in order that the apparatus may be flushed at any moment. This is frequently necessary in order to allow foreign particles as pieces of hop leaves ori other sediment which may collect at this point and obstruct the orifice to pass away.

To provide for proper movement of the regulating disk 4 and to enable it to resist the tendency ot' the liquid under pressure to move 4 pipe and atomizer are usually located at the top of the compartment or room. Hence I have placed a revoluble annular sleeve or cap 14 above the casting 2, and inclosing the coiled spring; said sleeve is secured to the casting by a holding screw which engages an annular slot. In addition I have pivoted aforked arm l5 to said sleeve, and arranged the end of the shorter arm to rest upon the upper extremity of the disk rod 3, while a chain 16 is affixed to the long arm; hence a pull upon the latter, which extends to one side of the room and hangs Within convenient reach of the Workmen enables the latter to pull it, when desired. Such act rocks the short arm anddepresses the rod 3 and disk 4 thereby enlarging the discharge orifice. Release of the chain allows the coiled spring to return the regulator disk to its proper position, the adjusting collar l0 coming in contact with Ithe boss in the casting. It is understood that the tension of the coiled spring must always exceed the pressure in the supply pipe in order to prevent the regulator disk from being moved except when the act of flushing is to be performed.

The purpose of the revoluble sleeve is to allow the forked arm to be positioned at any angle across the pipe and this is very necessary owing to the proximity of other pipes or objects, which otherwise might prevent proper action, and in this way allows the exible connection or chain to be conducted to any portion of the room.

What I claim is- 1. In apparatus for atomizing liquids, a tubular casting, a pendent cup-shaped delector plate removably attached, combined with a movable rod transversely through the casting, a regulator disk upon its lower extremity, an adjustable collar upon said rod to change the position of the disk, and a spring to hold said disk immovable against liquid pressure, substantially as set forth and stated.

2. In apparatus for atomizng liquids, the combination with a tube to receive liquid under pressure, a removable concavedeiiector plate, a similar shaped regulator disk therewithin, a movable rod adapted to carry said regulator disk, the plate and disk to co-operate but not to touch, mechanism for holding said disk fixed against the pressure of the liquid, and means to canse the disk to retreat from the defiector plate to tl'ush the apparatus, substantially as described.

3. An atomizer composed of a tube for liquid pressure, a pendent deiiector plate attached thereto and having portions of its circumference of different convexities, mechanism for holding said disk stationary against liquid pressure, and means for operating the disk A man ually to enlarge the discharge orifice and flush the atomizer, substantially as stated and explained.

In testimony whereof I affix my signature in presence of two witnesses. p
